［摘要］門式剛架作為經(jīng)典受力體系，以單榀剛架受力性能的可靠性為基礎(chǔ)，而門式剛架梁柱節(jié)點的剛性連接是組成剛架的基礎(chǔ)，所以梁柱節(jié)點的剛度對剛架至關(guān)重要。在新規(guī)程實施以前，老規(guī)程對梁柱節(jié)點的剛度并沒有明確要求，以致有些設(shè)計的節(jié)點達(dá)不到剛性節(jié)點要求。結(jié)合工程實例提出整改方法，取得了良好效果，同時對如何增強(qiáng)節(jié)點剛度進(jìn)行分析探討。

Abstract:As a classical mechanical system, portal rigid frame is based on the reliability of force performance for single pin frame, and rigid connection of portal frame beam-column joint is the foundation of rigid frame, so the beam column joints rigidity is very important for rigid frame. Before the implementation of the new regulations, the old rules have no clear requirements on stiffness of the beam-column joints, which lead to some design of the nodes can not reach the rigid node requirements. A solution was proposed and good effect was obtained combined with the engineering example, and the analysis of how to enhance the rigidity of the joints was discussed at the same time.
Keywords:portal rigid frame; beam-column joint; rigid node; rigidity
